On some old non-y2038-safe container runtimes, `statx` fails with `EPERM`, so use `crate::fs::statx` instead of calling the statx syscall directly. This includes code to check whether it was a "real" `EPERM` we should return to the user, or an `EPERM` which indicates that statx isn't supported, allowing rustix to fall back to the old non-y2038-safe syscalls. Also, update the crate-level comment mentionintg that rustix does sometimes do dynamic feature detection in order to support y2038 and LFS. And fix a copy and paste in a comment in `renameat2`.
